Police say they want the mum to know that she is currently being cared for and treated in hospital.

A statement from Helen Douglas, of North Wales Police, said: “We are concerned about the health of the mother of the baby girl and are appealing for her to come forward by contacting me, Helen, on 07835 923787. Likewise if you are a concerned friend, relative or neighbour of the mother you can also contact me on the same number.

"Alternatively, if anyone knows who the mother is or can provide any information which may assist in identifying her please contact North Wales Police by calling 101, quoting reference number V103529 . We want to ensure that the mother is provided with the medical support she needs.”

The baby was found in the bus stop outside the Magpie and Stump pub in Towyn, Conwy. The baby has been taken to Ysbyty Glan Clwyd.

Police were called just after 7.15am and part of the coastal road was closed off for a time.

A cordon has been in place around the bus shelter for most of the morning.

Police have been using a caravan at a local site as a mobile interview room.
